Corrosion Resistance for Aerospace
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
Corrosion Destroys Aerospace Components
Salt fog, fluids, and galvanic attack are constant threats
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Aerospace Corrosion Protection
Molecular-level barrier across all aerospace substrates
4,000+ Hours Salt Spray Resistance
ASTM B117 verified. 4x to 10x the protection of anodizing. Molecular-level ceramic barrier blocks moisture, chemicals, and ionic attack on flight-critical hardware.
Multi-Substrate Protection
Single coating system protects aluminum, steel, titanium, and composites. Eliminates galvanic corrosion risk at dissimilar metal interfaces in mixed-material aerospace assemblies.
Chemical & Fluid Resistance
Resists hydraulic fluids (Skydrol), de-icing agents, cleaning solvents, and fuel exposure. Maintains barrier integrity through the chemical environments aerospace components encounter daily.
Thin-Film Precision at 0.5-2 Mils
Maintains critical tolerances on precision aerospace hardware. No dimensional rework after coating. Lighter than powder coating alternatives by 60-80%.
Corrosion Resistance Specifications
How We Deliver Aerospace Corrosion Protection
AS9100 controlled from surface preparation through final verification
Substrate Analysis & Preparation
Alloy identification determines optimal preparation protocol. Controlled media blasting creates ideal adhesion profile. Ultrasonic cleaning removes contaminants. Critical surfaces masked per engineering requirements.
Ceramic Coating Application
Cerakote applied in controlled layers at specified thickness. Full coverage verified on complex aerospace geometries. DFT measurements confirm 0.5-2 mil specification on each component.
Cure, Test & Document
Temperature-controlled cure cycle. Post-cure adhesion testing (cross-hatch per ASTM D3359). Thickness verification. Certificate of Conformance with material traceability, test data, and lot documentation.
Verified Corrosion Performance Data
All corrosion claims verified through independent ASTM B117 salt spray testing, not manufacturer assertions. Test data documented under AS9100 process controls.
Real-world protection
Cerakote-coated aerospace components maintain barrier integrity through salt fog, fluid exposure, and thermal cycling that destroys anodized and painted finishes in a fraction of the time.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Metal additive manufactured parts in stainless steel and titanium often have surface porosity that makes them more susceptible to corrosion than wrought equivalents. ColoradoKote's passivation plus Cerakote stack seals this porosity and provides 3,000-hour salt spray protection, qualifying AM parts for corrosive industrial service. This post-processing capability is what makes the difference between AM prototypes and AM production parts.
MIL-DTL-5541 Type I chemical conversion coating delivers 168-240+ hours of salt spray resistance per ASTM B117, while Type II non-chromate conversion provides 96-168+ hours. These are standalone results without any topcoat. When your application demands maximum corrosion protection, pairing conversion coating with Cerakote extends salt spray resistance to 3,000 hours (ASTM B117) in a total coating thickness of just 0.5-2 mils.
Standard turnaround is 14 days from receipt of parts, with 3-day and 7-day expedited options available for maintenance-critical components. We understand that equipment downtime costs money, and our scheduling system prioritizes expedited orders accordingly. Contact us at the time of quoting to discuss your maintenance window and we will confirm availability for your timeline.
Cerakote delivers 160/160 inch-pound impact resistance, meaning it withstands significant mechanical shock from both the coated side and reverse side without cracking, chipping, or delaminating. This dual-direction impact resistance is critical for components subject to drops, tool strikes, vibration, and mechanical loading during service. The coating flexes with the substrate rather than fracturing like brittle hard coatings.
Chemical conversion coating per MIL-DTL-5541 provides a critical corrosion barrier for aluminum components exposed to oil and gas environments, including saltwater, H2S, and hydrocarbon exposure. Type I delivers 168-240+ hours of salt spray resistance (ASTM B117) as a standalone treatment. For extreme downhole or offshore conditions, we recommend adding a Cerakote topcoat for 3,000 hours of salt spray protection at just 0.5-2 mils.
